I chose the Marines because of the varying types of Justice, the suits the Admirals and Vice Admirals wear, and alias names of the Admirals. It’s also fun to see that there are many Marines with their own unique and somewhat quirky personalities like Garp’s care free yet responsible nature, Sakazuki’s sternness and no nonsense behavior, Fujitora’s high morality, Tsuru’s wisdom, etc. Depending on their rank, they can have their own attire which kind of tells you what kind of person they are like Fujitora’s yukata, Vice Admiral Bastille’s mask, and Smoker’s jacket. To me, it’s nice to see that, despite being a military force for an entity like the World Government, they aren’t all these blunt, boring soldiers with no personality or interesting nature. They aren’t forced to think, act, feel, dress, and be the same person.
